To all whom it may concern Be it known that I, GEORGE A. hwat'rpa citizen of the United States, residing at Minneapolis, in the county of Hennepin and State. of hfinnesota have invented certain new and useful Improvements in Adjustable Storm-lVindow Holders;' and I'do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a window holder and is particularly designed to be used with a storm window or other outside window or screen structure. In the colder portions of a country, storm windows are used during the wlnter season and such windows are usually secured in position by being hinged or pivoted at their upper ends. These windows are only opened slightly and when so open are merely swung outwardly at their bottom portion.

It is an object of this invention to provide a holder for such windows, whereby the same can. be opened to any desired'extent and held firmly in such position. This and otheradvantages of the invention will be apparent from the following description made in connection with the accompanying device of the invention in relation thereto,

said window being shown in an open position by dotted'lines. i 1 V Referring to the drawings:

The device is seen to consist of a plate 1, having a raised central portion and apertured end portions adapted 'to receive. 'attaching screws by which the plate is firmly with an aperture at its central raised portion and a headed screw 2 is disposed in this aperture, ltsthreaded portlon of which ex-. tends upwardly and receives in superposed.

relation above said plate,,the apertured ends of two flat link members 3 and 4. washer and set forth in the appended claims; secured to the sill or outer portion; of the window frame. This plate is also provided link and jawingedclamping nut 5:i's thread ed 'on the screw above tl1'ewasher. The. links 3} and l'extend in'oppos-it'e directions {is also placed on the screw 2 above the upper' V 7 and havepivoted thereto at their outer ends the ends ofsimilar links 5 and 6. The links 5 and 6 are also oppositely disposed and in the closed position of the device shown in F ig.- I extend at a slight angle to the links 3 and 4 to form a closed parallelogram. The other ends of links 5 and 6 are aper' tured and in alignment and are pivoted to an apertured'lugextending from the bottom of a plate member 7, which is-provided with; suitable holds for attaclnnentto the lower sash 8 the window. The upper portion 7 of the member 7 is tapered and rounded at its end and bent outwardly in a curve. to form a suitable finger hold for manipulating the window. The operation of the device is as follows: 7

The window 8 which asshownin Fig. 3 is pivoted at its upper portion will be swung outwardly to'the desired positionby operator grasping the finger hold of member 7 -The links'willthen swing on their various pivots and being distended as shown intFig.

l. lhes e links, it will be noted, form a' 85.

lazy tong'structure, hen the window is open to the desired position, the clamp nut 5, whichpreviously has beenloosened, will now be tightened. The window will be held securely in the desiredposition. As d'e-' sired, the'portion of the link' 3 which contactswitnplate 1 and link i may be some; what loosened or corrugated so that when firmly held in frictional. engagement:

It 15 thus seen that the applicant has produced a simple and 'efiicient window holder the screw 5 is tightened. the'parts will be. i

and one which can be quickly applied and made inthe form and details of the device will require very little attention. It will be" i without departing from the scope" of the applicants invention, which generally stated consists in the matter shown and described 7 c onv erging,a bracketsecured to the window frame, and a single bolt forming both the connecting means of said last mentioned links and bracket and a locking means for portion locking said sash in various open positions and also in closed position.

2. The structure set forth in claim 1, said bracket secured to the window sash having a projecting portion to which the -first mentioned links are pivoted having an outwardly and downwardly curved portion forming a finger hold for moving said windows;

3. A window holderhaving in combination, two pairs of plain links pivoted together to form a lazy tong structure, a

bracket adapted o be secured to the window sash to which the ends of one pair of links are pivoted, a bracket adapted to be secured to the Window frame, a single pivot, connectingdie ends of said second pair of links and said latter bracket, said pivot being threaded, and a clamping nut screwed thereon adapted to contact the ends of said links and clani the same a 'ainst said bracket to positively lock said sash in various open r positions and also in closed position.

In testimony whereof I affix my signature.

GEORGE A. AWALT.
